ToaZZ whom z't may concern:

Be it known that I, THOMAS A. JENKINS, ,a citizen of the UnitedStates, residing at Jersey City, in the county of Hudson and 5 State of New Jersey,have inventedcertain new and luseful `Improvements in Ventition. i

This invention relates to ventilators generally, and more particularly to a type of such ventilators which is adapted for use in the ventilating lof buildings of -all 'descriptions, vrailway cars, tube or tunnel cars, Yautomobiles,vehicles, aircraftof all descriptions, ships of all descriptions, and -in any other place where it is desirable, necessary .orripossible tozventilate.

Anobject of the-invention is to provide ,talltakeni-on the line 8 8 of Fig. 7,

for `ventilators `ofl ther-class set forth, and

r which may be inthe form of windows, doors,

`partitions,tunnels, skylights and the like.

Another object ofthe invention is to provide for the forms of ventilators as herein before stated, and which are so formed or 42li otherwise constructed and arranged as to be perfectly air-tight, when inoperative.

f A .further object ofthe invention is to provide for ventilators ofthe `class set-forth,

wherein the same are each constructed and.

arranged to provide a plurality of movable sections which are capable of beingmanipulated from full closedto fullopen position, or adjusted to any desired deg-ree atpoints between such full .closed .and open positions,

.35 whereby an interior may be ventilated as may be desired or necessary.

Another and equally important vobject of the invention is to provide for ventilators of the type mentioned, and one of a con- `4,0 struction `and arrangement such as readily adapts the same for substitution in lieu of the present 'known .window sash structures, the samey functioning as the daylighting medium of the interior of aroom, compartment or the like. and in a manner to be rain Y and air proof wheninoperative and .capable of manipulation for the desired ventilating purposes, and which, when` made from, an opaque glass, dispenses with the 4useof ,5.0 shades and curtains whereby to give thejdesired Vprivacy to the interior. i

With the foregoing and other objects in view, .the invention .resides in the certain `novel and useful construction and arrangeit met .ef parte es will be hereinafter alors fully described, set forth in the appended claim, and illustrated in the accompanying drawings, in which Figure `l is an elevation of the ventilator, Figure 2 is a fragmentary sectional View y l taken on the line 2`2 of Figure 3, lators, of which the` following is a-specificav lFigure 3 is'an enlarged fragmentary vertical section taken on the line 3 3 of Fig. l,

'Figure vl8 is a fragmentary `sectional de- `Figure ,9 .is a 4 side elevation and an end Eelevation `of the clips or retainers for sup- Lporting,and manipulating the glass ventilating strips.

In IFigures 1 to 9v, inclusive, I have shown an adjustable type of ventilator, and the samecomprises the frame 11 formed of upper 4and lower .bars .and .oppositely disposed vertical ys ide bars 16, the .latter bars 16 beling channeled as fat 16 Vthroughout the length .of their ,inner opposed faces and fQFIlOl to provide removable front wall portions 16 normally rclosing one side of the channels 16. Mounted within the channels 16 ,are metal casings 1:9 substantially rec-- `tangular in cross section and of -a-n equal height and of an -equal length to that of the channels 16', but of a depth less than that of the same. The opening of the frame l1 'is preferably divided on its `vertical center vby a `partit-ion bar or strip 40 to provide for .two rectangular ventilator openings adapted to be normally closed by 'a series of slats, panels or strips 15, the latter being preferably of glass, either transparent or opaque. These sla-ts or strips l5 are placed position horizontallyfof` the ventilator through of air or rain, or any other suitable method may be resorted to for the accomplishment of the desired purposes. The opposite end edges of the slats, panels or strips are retainedin` clip'` members 1f? which are provided with pivot studs 18, certain of which studs are adapted for engagement in the opposite sides of the partitionbars or strips 10, in which Vcase the studs 18 are terminated as at 41, (FigureQ), while those engaged in pivot openings 20, of the metal casings 19, are groovedas atf13, the grooved portions of the saine projecting for a distance within the interior of the casings as is clearly shown in Figures @i and 5 of the drawings.

, For operating the pivoted slats'15` to open and closed positions, a flexible element 23, such as a wirecable or cord, is looped upon itself within each of the metal casings 19, and intermediate portions of the same are wound within the grooves i3 of the longer of the pivot studs 1S, and are trained over drums or rollers 28 located at the upper and lower ends of the casings l19, it being here notedv that the lower ends of the casing 19 are projected into recesses 11"i formed downwardly of the top edge of the bottom bar of the vertical frame of the ventilator frame 11 in line with the channelsV 16- of the side bars thereof. The lower ofI the free end portions of the cables 23 areliwound as at le around the shank portions of the operating knobs `or members 21,v which are slidably mounted for a sutiicient vertical movement in slotways 27, formed in removable face plates 29 secured over openings at the front of the bottom of the bar of the frame 11. The shank portions of the knobs 21 project into the recesses 11a, and the eXtreme free end portions of thecables 23 are connected together by means of tensionrdevices or springs 24.' The shank portions of the operating knobs or members 21 are held in the slotways 27 by means of washers 25 arranged thereon in abutting relation with respect to the inner face of the face plates 29, which, in turn,V are secured on the shanks by means of lock collars 26.

In the operation of this form of the inl vention, the ventilator is positioned within a light opening of a building or the like, either singly, one closing the lower half portion or the upper half portion thereof, and in either instance, upon the raisingor lowering of the'sashes,`the slats or strips 15 are to be manipulated to open, partially open, or fully closed positions by sliding the knobs or members 21 in the slotways 27 of the face plate 29, the slats or strips 15 being closed when the knob 21 is positioned atthe upper end of the slotways 27 in the present instance land as shown in Figure 5. With the knobs 21 in their normal upper positions, and it is desired to open theventilator another.

slats or strips 15, a downward pull on the knobs 21, exerts a pull von the flexible elements or cables 23and the pivots 18 are rotated to move the slats or strips 15 to the desired or open position, the latter position provided and which is shiftably supported in the casing 19and is adapted to be moved to a position to bear against the side of a clip 17, to arrest movement thereof. EX- tended inthe apertured slide 22', is a cam shaped head 4:5 of a` locking bolt 21A mounted in a side bar 16, of frame 11. The slide 22', when the bolt 21A is shifted in one direction is moved tov the position shown in Figure 2 to hold the slats 15`from moving and which also prevent the actuation of the operating mechanism for the slats 15, and when the bolt 21A is shiftedl in the opposite direction, the slide 22 is moved lclear of the clip 17 so that the latter can be shifted by its operating mechanism.

A. pin 32 is associated with the bolt 21A and which engages with the stop 33 for limiting the turning movement of the bolt. The pin 32 isso disposed with respect to the stop 33, thatpthe bolt can turn approximately 180 degrees which is sufficient to affect the proper positioning of the bolt 21A for the purpose intended As shown in Figures 1,7 and 8, the invention contemplates the provision of an air iiltering means, and in this instance, a sheet of suitable fabric 30 is to be positioned over the ventilative opening or open ings, as by va series of buttons' or screws 12 being secured at the corners and intermediate parts on the frame or frames thereof, suitable threaded sockets 14 being positioned in openings in the latter for their reception, and the "sheet of fabric formed with buttonholesor the like 34 to be removably engaged over` the heads of the buttons'or screws. `Washers` 13 are interposed between the heads of the screws 12 and 30. These sheets of fabric 30 are to be of a nature as to be readily laundered, and interchanged one for Also, sheets of wire mesh fabric or screening may be attached in the same manner as thefabrics to render the ventilators iiy and insect proof. y

Itis within the scope of the present invention to utilize the ventilator structures as substitutes for the now used window sash of houses, buildings, vehicles and the like, and forthis purpose the glass panels or strips 15 are to be made of any kind of ius glass, or other suitable transparent or opaque material, which may be either clear glass for ready observation through the same, or entirely opaque, or in any combination of clear and opaque or colored glass, in the latter cases, and in some instances, the usual Window shades may be entirely dispensed with as has been hereinbefore explained.

It is Well understood that while I have described and illustrated the preferred embodiment of my ventilator construction in specific terms and details of construction, arrangement and operation, various changes in and modifications of the same may be resorted to Without departing from the spirit of the invention, or the scope of the claim appended hereto.

wel

Having thus fully described the invention, what is claimed is A ventilator comprising a frame, superposed clips arranged at each side of the frame and provided with extended pivots supported Within the frame, overlapping slats having end engagement With said clips, flexible elements engaging with the extended pivots of the clips, means connected with the flexible elements Jfor operating them, thereby moving said slats, slidable elements mounted in said frame and adapted to engage certain of said clips to arrest movement of the slats, and cam members for operating said slidable elements.

In testimony whereof, I affix my signature hereto.

THOMAS A. JENKINS.
